Info about Opus Magnum: De Re Metallica:

Official game description:
An independent story set before the events of _Opus Magnum_, **De Re Metallica** follows a maverick alchemical researcher named Saverio Daas, who believes he can unlock metallurgical secrets that even the Imperial Academy has not uncovered! Along the way he’ll clash with established orthodoxy, bicker with his assistant, and attract attention from the Great Houses. What happens when a new invention becomes worth much more than its weight in gold?
**De Re Metallica** is an independent mini-campaign, and includes:
*   Three new chapters of puzzles, with difficulty similar to the second half of _Opus Magnum_
*   Three new glyphs, with the ability to manipulate metals in heretofore unknown ways
*   New story, cutscenes, and music from the original writer and composer Matthew S. Burns
*   A new "House Colvan" variant of _Sigmar's Garden_, where metals are matched in sequential pairs

  - Reasoning: The DLC campaign completion reports cluster around 4-5 hours: one review says 4-5 hours, another says the campaign is about 5 hours, and a third reports about 3 hours. A few longer reports exist (about 12 hours and about 25 hours), so I use 5 hours as a representative typical completion for both gameCompletion and storyCompletion, since the DLC campaign is its story. No review gives a typical session length. Reviews mention countless hours optimizing solutions and solution golfing, but no numeric endgame duration is provided, so endgame is null.

Common complaints:
- DLC content is too short (weight 0.56): Many reviewers report the DLC can be finished in 3-5 hours, feeling too brief and lacking post-campaign content. This is a common complaint about the overall length.
- Difficulty is inconsistent (weight 0.4): Some players find the DLC easier than the base game, while others note a definite increase in difficulty, and some puzzles feel constrained or too easy. This variability can be frustrating.
- New glyph mechanisms are unwieldy (weight 0.31): The new runes for splitting and copying metals are considered mysterious, tedious, and take up grid space, complicating minimal cycle and area designs. This adds unnecessary complexity.
- Poor value for money (weight 0.27): Several players feel the DLC is overpriced relative to its length, especially when on sale for the same price as the base game. This ties into the perception of limited content.
- New glyphs are too powerful (weight 0.25): The three new runes, especially mercury turning into all metals, are considered overpowered and make minimal cost challenges much easier. This can trivialize some puzzles.
- Story is forgettable and sparse (weight 0.25): The scenario is forgettable, does not go beyond explaining experiments, and there is not enough story compared to the base game. This leaves players wanting more narrative depth.
- Puzzle variety is limited (weight 0.2): A large portion of puzzles involve spinning a central atom while attaching things, and there is a heavy emphasis on metals. This repetition reduces variety.
- Lack of post-campaign content (weight 0.2): There are no appendix challenges, and players desire more post-campaign content such as DLC-specific journal entries. This contributes to the feeling that the DLC is slight.
- Technical issues on high-res screens (weight 0.14): The game is still bad on high-resolution screens, with no UI scaling option, requiring players to lower resolution on 4K monitors. This affects usability.

- New glyphs lack tutorial depth (weight 0.08): There is little room to grow and learn the new glyphs due to only one simple level before harder ones. This makes the learning curve steep.
- Base game puzzles were tedious (weight 0.08): Most base game puzzles were tedious, which may affect overall enjoyment. This is a general complaint not specific to the DLC.
- New songs missing on Spotify (weight 0.07): The new songs are not available on Spotify, which is a minor issue for some players. This is a niche complaint.
